VAPORIZER.

Specification of Letters Patent.

atented Sept. 9', 1913.

Application filed March 24, 1913. Sera1Nof756,376.

To all whom it may concern.'

Be it known that I, GEORGE A. ARNOLD, of Middletown, in the county ofMiddlesex and State of Connecticut, have invented certain new and usefulImprovements in Vaporizers, oi? which the following is a specification,reference being had to the accompanying drawings, forming part thereof.Y

This invention has reference .to improvements in vaporizers andparticularly to Vaporizers adapted to 4supply heat te 4air or other iuidVpassing therethrough.

One object of the invention is to so censtruct a vapori/lier having aseries of heat radiating units that air Aor other Huid in its passagethrough the `'vaporifzer ject'ed lto the `most :intense heat at or.about the initial point of suchpassage and thereaft-er be caused tocirculate aboutvthe heating units of less intensity.

Another object of the, invention is to so construct a vaporizer of thisnature Ithat a series ofheating units may be sustained by membersmounted for removal with a wall of the vaporizer chamber and positionedthereby relative to the vaporizer iinlet.

Other objects of the invention Vwill apthe 'following description.

The invention consists in the novel construction and arrangement of theheat .radiating units.

The invention also consists in such other novel features of constructionand conibination of parts as shall hereinafter be more 'fully describedand pointed out in the claims. y

Figure 1, represents a longitudinal sectional view oi the improvedvaporizer as taken on a line 1-1 Fig. 2. Fig. 2, -represents an end viewof the vaporizer. Fig. 3, represents a crosslsectional view taken online 3-3 Fig. 1 looking in the direction indicated by the arrows of'saidline.

Similar el aracters of reference designate corresponding partsthroughout.

Thisimproved vaporize: is particularly adapted to be attached to andform part of the air intake pipe or Hue of a carburetor for a combustionengine or to be applied as a conduit between the carbureter and theengine but, in its broad principle of application, this vaporizermay beutilized in any manner to supply heat to Huid passing therethrough.

shall be -sub- VThese ln Vthe simple embodiment ofthe invention of whichthe preferred form is shown in ythe vdraiif'ings 5 indicates the wall ofthe y vaporiaer chamber which, preferably,- is cylindrical in shape andis -supplied with the heat insulating -lining6, usually of asbestos. 7and 8 are the .head `members of the vaporizer and are furnished withcentral openings vwhich are delined by clampingfcollars 9 and 10 adapted"to be clamped Aonto the ends of pipe members by the tightening ot theirscrews 11 and 12. The peripheriesot said vmember-s 7 and 8 haverespectively the lips 1-3 and 14 which embrace the wall of chamber 5 andhave-ears 15, 15 and 16, 16 through which extend screws 17, 17 and 18,18 the inner ends of which are secured in perforations of the wallof'chamber 5.

Mounted in diametrically positioned openings of the head 8 are thebushings 19, 19 of hard rubber or of some other electrical insulation.Secured in-placein the bores of said bushings are the terminals 20, 20preferably of copper and of comparatively large size. These terminalsare bent inward, toward each other, and have the ,members 21, 21 whichare approximately fparallel. vision 'is made for limiting the movementof said terminals 20, 20 through the bushings 19, 19 by reducing the endportions of the terminals to form the shoulders22, 22 which bear againstsaid bushings while the exterior end portions of said terminals arefurnished with the wire-binding nuts 23, 23. Secured to the members 21,21 of said terminals 20, 20 are the disk delectors 24, 25 and 26 whichpreferably are circular in shape and of different size, the diskdefiector 24 being `pref-- erably smaller than the deflectors 25 and 26.delectors are of cast plaster or other suitable material adapted toresist heat and to form electric insulators whereby theheatresistancematerial and the length of wire in saidcoils differs, thelength of wire in coil 27 being less'than that in coil 28 and thatinturn being of less length than that of coill29, so that the coils 27 and28 are adapted to be ment or coil 27, the thus heated fluid raised to'ahigher temperature than coil 29 l-bythe same amount of electric current.The

convolutions of the Wire of coils 27 and 28 have the interposed asbestosor other heat resisting material 30 and 31 while the conbe deflected bythe delector 24 and will pass over and receive heat from its heatingelewillv the vaporizer cham-v berV through the openingof its head 8.will expand and enter between defiectors 24 Vand 25 and will again bedirected toward the wall of the chamber and will pass over the coil 27and receiving heat therefrom will expand more readily; a likeopeationoccurring as the expanded fluid is again deected by deector 26 with theaddition that the expanded` fluid maycirculate between vand around theconvolutions of the coil 29V which tends to maintain the temperature ofthe Huid andv distribute the heat more evenly therethrough.

Having thus described my invention I claim as new and desire to secureby Letters Patent.

l; A vaporizer of the nature described comprising a cylindricalchamber,'a pair of clampin collars havin members removably mounteton'said cham er and forming the ends thereof, a pair of electric conductorscarried by a member of one of said collars.4

Copies ofthis patent may be obtained for ve cents each, by addressingthe electrical heating and forming vsupporting members within saidchamber, a series of deflectors of electricl insulating material mountedon said conductors, and a series of electric resistance coils carried bysaid deiiectors, whereby said clampingA collar, conductors anddeflectors form a removable unit. Y

A2. A vaporizer of the nature described comprising a cylindricalchamber, a. head secured to said chamber, a pair of electric terminalslextendingthrough said head, a series of deiiectors mounted on saidterminals and increasing progressively in diameter, and electricresistance coils embracing said deflectors and in electrical connectionwith said terminals, one of said coils having its convolut-ions packedwith heat resisting .material and another of said coils being open forthe circulation of uid therebetween.

3. The combination with a cylindrical chamber, a head secured -to suchchamber and having an inlet opening-and a clamping collar, a pair ofelectric terminals extending through said head, a deiector mounted onsaid terminals and in line with said inlet, an coil of comparativelyhigh intensity mounted on said detlector and electrically connected pairof delectors minals at a distance from said first detlector and havingelectrical heating coils of progressively decreasing intenslty invelectric connection with said terminals substantially as described.
